FAUCET.

Specification of Letters Patent.

Application filed March 26, 1908. Serial No. 423,405.

To all whom it may concern:

Be it known that I, HENRY F. SOI-IROEDER, a citizen of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented a certain new and useful Improvement in Faucets, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

This invention relates to faucets of the type employed in connectionwith sinks and basins, and particularly those wherein a rubber valvebody is moved toward and from a valve seat, such movement beinglongitudinally of the water-way of the faucet. Such valve bodies arecommonly operated by means of a rotary plug or shaft to one end of whichan operating handle is attached and having at its opposite end a crankconnected to the valve body by means of a link. In the operation offaucets of this type, it has been found that they are liable to producewater-hammer and that the looseness of the link causes a disagreeablerattling during the flow of water through the faucet. Rubber isordinarily employed in the construction of the valve body. l/Vhere softrubber is employed, the valve body swells, and this swelling adds to thewater-hammer effect referred to. It has been proposed to obviate thisswelling by employing hard rubber as the material for the valve body,but the latter material breaks in use and renders the valve leaky.

It is the object of my invention to produce a faucet of the typedescribed which shall be free from the objections noted and which shallbe simple and economical in construction and elficient in use. Iaccomplish these results by the construction e1nbodied in the drawingsforming a part hereof, wherein- Figure 1 represents a view, partly inside elevation and partly in section, of a faucet constructed inaccordance with my invention; Fig. 2 represents a view, partly in bottomplan and partly in section, of the faucet shown in Fig. 1; and Fig. 3represents a perspective view of the sleeve which I employ in connectionwith my valve.

Generally speaking, the invention may be defined as consisting of thecombinations of elements embodied 1n the claims hereto anneXed.

Describing the parts by reference characters, 1 denotes the body of thefaucet, the

same being preferably of cast brass and having a nozzle 2 and anupwardly projecting integral sleeve 3 within which there is journaled ashaft 4 having at the lower end thereof the crank 5. The rear or inletportion of the faucet casing is provided with an outwardly projectingflange 6 and has beyond such flange two exteriorly threaded portions 7and 8, the latter portion being of less diameter than the former andhaving its inner surface beveled to form a valve seat 9 at the extremerear or inlet end of the faucet body.

10 denotes an enlarged sleeve having at one end thereof a threadedconnection 11 for the supply pipe and having its other end rovided withan internal thread adapting it to be fitted to the portion 7 of thefaucet body.

12 denotes a cap or casing of considerably smaller diameter than theinternal diameter of 10, having its rear end closed and its front endprovided with an internal thread by means of which it is fitted to thereduced portion 8 of the faucet body. Casing 12 is providedwith anannular series of ports 13 extending therearound and located immediatelyat the rear ofthe valve seat 9 formed on the inlet end of the faucetbody.

The valve is mounted within the cap or casing 12 and comprises asoft-rubber body 14; having applied to the rear end thereof a metalliccap 15 which forms a backing for a nut 16 on the threaded end of link17, which extends through the valve body and connected at its forwardend to the crank 5. The link 17 is provided with a shoulder 18 betweenwhich and the nut 16 the valve body 14 is clamped; also with a pair ofoppositely-projecting lugs 19 which are adapted to center said link withreference to the faucet body.

\Vith the construction above described, the operation will be asfollows:-By rotating the operating handle 20 in either direction fromthat shown in Fig. 1, the valve body 14 will be moved rearwardly andwater will flow freely through the ports 13. On closing the valve, theflow of water through ports 13 is cut off, but without any pressurebeing exerted by the water upon the rear end of the valve-body. In fact,the rearward and upward inclination of the valve-body from ports 13causes the water flowing through said ports to resist, rather than aid,the closing of the valve. As there is gen- Patented Dec. 13, 1910.

- vention of water hammer.

lost-motion between the 17, the pressure of the water on the rear end ofthe valve body 14 in constructions heretofore in general use tends toclose the valve quickly and produce water-hammer. This effect isincreased, where soft-rubber is employed for the valve body, by theswelling of such body. In my construction, however, the water neverimpinges upon the rear end of the valve body and any tendency of thevalve body to swell is prevented by the inclosing casing 12.Furthermore, the sleeve 10, being of considerably greater internaldiameter than the diameter of casing 12, provides an expansion chamberfor the water flowing through the faucet, which also contributes to thepre- The casing or cap 1:2 serves as a guide for the valve-body,insuring accurate seating of the same and, as the casing fits theexterior of the body more or less closely, any tendency of the link tooscillate and rattle within the faucet body is overcome.

Having thus described my invention, 1 claim:

1. In a faucet,the combination of a faucet body having its rear or inletend beveled to form a tapered valve seat and provided outside of suchend portion with a thread and having. a thread in front of the formerthread, a casing fitted to the first thread erally more or less crank 5and link and provided adjacent to the inlet end of the body with aplurality of ports, said casing being closed at its rear end, a secondcasing surrounding the former casing and threaded on to the secondthread of the body and forming with the former casing a chamber, a valvebody of soft rubber mounted in the first mentioned casing and having atapered surface adapted to engage the tapered seat on the end of thefaucet body, a link connected with the valve body, and a faucet shaftconnected with said link.

2. In a faucet, the combination of a body having a passageway thereinand provided at its rear or inlet end with a beveled seat, a casingprojecting rearwardly from said seat and provided adjacent to said seatwith a series of apertures, a casing surrounding the first mentionedcasing and forming therewith a chamber, a soft rubber valve body mountedin the first mentioned casing and having a tapered surface extendingrearwardly of said apertures and adapted to engage the beveled seat, andmeans for moving said valve body toward and from its seat.

In testimony whereof, I hereunto afiiX my signature in the presence oftwo witnesses.
